Ceiling Method

Decimal.Ceiling Method

Returns the smallest integral value that is greater than or equal to the specified decimal number.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static decimal Ceiling(
	decimal d
)

Parameters

d
Type: System.Decimal

A decimal number.

Return Value

Type: System.Decimal
The smallest integral value that is greater than or equal to the d parameter. Note that this method returns a Decimal instead of an integral type.

The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding toward positive infinity. In other words, if d is positive, the presence of any fractional component causes d to be rounded to the next highest integer. If d is negative, the rounding operation causes any fractional component of d to be discarded. The operation of this method differs from the Floor method, which supports rounding toward negative infinity.

The following example illustrates the Ceiling method and contrasts it with the Floor method.

using System;

public class Example
{
   public static void Main()
   {
      decimal[] values = {12.6m, 12.1m, 9.5m, 8.16m, .1m, -.1m,  -1.1m, 
                          -1.9m, -3.9m};
      Console.WriteLine("{0,-8} {1,10} {2,10}\n", 
                        "Value", "Ceiling", "Floor");
      foreach (decimal value in values)
      Console.WriteLine("{0,-8} {1,10} {2,10}", value,
                        Decimal.Ceiling(value), Decimal.Floor(value));

   }
}
// The example displays the following output: 
//       Value       Ceiling      Floor 
//        
//       12.6             13         12 
//       12.1             13         12 
//       9.5              10          9 
//       8.16              9          8 
//       0.1               1          0 
//       -0.1              0         -1 
//       -1.1             -1         -2 
//       -1.9             -1         -2 
//       -3.9             -3         -4
